beego: support more router

Browse Source 
//design model
	beego.Get(router, beego.FilterFunc)
	beego.Post(router, beego.FilterFunc)
	beego.Put(router, beego.FilterFunc)
	beego.Head(router, beego.FilterFunc)
	beego.Options(router, beego.FilterFunc)
	beego.Delete(router, beego.FilterFunc)
	beego.Handler(router, http.Handler)

//example

beego.Get("/user", func(ctx *context.Context) {
	ctx.Output.Body([]byte("Get userlist"))
})

beego.Post("/user", func(ctx *context.Context) {
	ctx.Output.Body([]byte("add userlist"))
})

beego.Delete("/user/:id", func(ctx *context.Context) {
	ctx.Output.Body([]byte([]byte(ctx.Input.Param(":id")))
})

import (
    "http"
    "github.com/gorilla/rpc"
    "github.com/gorilla/rpc/json"

func init() {
    s := rpc.NewServer()
    s.RegisterCodec(json.NewCodec(), "application/json")
    s.RegisterService(new(HelloService), "")
    beego.Handler("/rpc", s)
